The '''Sapper''', mentioned in the ''Sentry Gun Operational Guide'' as the '''FM/AM Ultra-Electro Sapper''', is the default [[Weapons#spysecondary|secondary weapon]] of the [[Spy]]. It is a small box inscribed '{{botignore|Electro-Sapper}}' and sports a dial and  switches. It also features two clamps that are deployed when used.

The sole function of the Sapper is to destroy an [[Engineer]]'s [[buildings]]. Should the player select the weapon and stand near an enemy structure, they will be able to see a white outline of the Sapper on the building, indicating that it is in range and can be sapped. Pressing the primary fire key, default left-click, will attach the weapon, and the building will slowly be damaged until it is destroyed. A sapped building will cease to function; [[Sentry Gun]]s will not fire, [[Dispenser]]s will not heal or dispense ammo and [[Teleporter]]s will not teleport. When applied to buildings, the Sapper will produce electrical sparks and a loud hissing noise. When a Sapper is attached to one end of a Teleporter, another Sapper is automatically placed on the other end of the Teleporter, if it exists. If the Spy is disguised, the disguise class will play a distinct, unique animation of placing the device on the building.

Once the building is being sapped, the Engineer owner will be alerted to it in his HUD, and will automatically play a voice clip alerting nearby players of the building's predicament. Engineers can remove a Sapper with two hits from their melee weapon. When a Sapper is attacked, the Spy player will be notified by a similar alert in their HUD. If an Engineer removes a Sapper from a Teleporter, the Sapper at the other end is also removed. If another Engineer strikes the Sapper first, he can get an [[Kill assist|assist]] for the Sapper kill, and a Medic healing an Engineer can also score an assist in this way. [[Pyro]]s equipped with the [[Homewrecker]] can also destroy Sappers in one hit if they happen upon them. Enemies focused on removing Sappers may leave themselves open to a [[backstab]] or [[headshot]], allowing the Spy or a teammate to distract and dispose of enemies in addition to the building in question.

Unlike the Spy's other weapons, using a Sapper does not cause him to lose his disguise.
  
−
A small gauge is visible on the Sapper when it is being carried; it serves no purpose other than aesthetics. The Sapper has infinite ammunition and no discernible "cooldown" time; Sappers can be placed on a building faster than an Engineer can repair the damage each one causes, which guarantees the building will be destroyed if the Spy is not dealt with. This tactic seldom works if there are multiple players around.

Sapped Sentry Guns take 33% less damage from the Spy who applied the Sapper, such as when shooting them with a Revolver. Dispensers and Teleporters take normal damage.

== In Mann vs. Machine ==
 +
In [[Mann vs. Machine]], Sappers can be attached to [[robots]], [[stun]]ning them (and, if [[Upgrade Station|upgraded]], any other robots nearby). Robots stunned this way can be [[backstab]]bed from any angle. Sappers do not damage robots - they only disable them for 4-7 seconds depending on how many Robot Sapper Power upgrades have been purchased. Giants, being immune to stun, are only slowed down and can still attack players. Sapping an [[Engineer Robot]]'s buildings works as usual, however only one building can be sapped at a time.
 +
 +
Unlike regular multiplayer, sapping either a robot or a building requires the Sapper to recharge for 15 seconds before another one can be deployed.
 +
 +
The Sapper can be instantly recharged with a [[Power Up Canteen|Ammo and Clip Refill]] canteen; however, if the Spy has placed a Sapper on a robot or building, he is unable to deploy it until the previous Sapper is no longer active (either all the objects it was applied to are destroyed or the effect time expires).

This article is about the stock building item for the Spy. For other sappers, see Sapper (disambiguation).
"Sapped" redirects here. You may have been looking for the unusual effect.
The silhouette shows that a Sapper can be applied to the building. Note the needle gauge is in the red.
A level 1 Sentry being sapped.

Spy's sappin' mah sentry!

The Sapper, mentioned in the Sentry Operating Manual as the AM/FM Ultra-Sapper, is the default building weapon for the Spy. It is a small electric generator inscribed 'ELECTRO-SAPPER', with a carrying handle, two long yellow wires and a meter. It also features two clamps that are deployed when used.

The sole function of the Sapper is to destroy an Engineer's buildings. Should the player select the weapon and stand near an enemy structure, they are able to see a white outline of the Sapper on the building, indicating that it is in range and can be sapped. Additionally, the needle on the gauge moves to the right red zone. Pressing the primary fire key (default key: MOUSE1) attaches the weapon, and the building is slowly damaged until it is destroyed. A sapped building immediately ceases to function; Sentry Guns do not fire, Dispensers do not heal or dispense ammo, and Teleporters do not teleport. The Engineer is also unable to use his Destruction PDA to self-destruct a sapped building. When applied to buildings, the Sapper produces electrical sparks and a loud hissing noise. When a Sapper is attached to one end of a Teleporter, another Sapper is automatically placed on the other end of the Teleporter, if it exists and is not in building progress. If the Spy is disguised, the disguise class plays a distinct, unique animation of placing the device on the building. Unlike the Spy's other weapons, using a Sapper does not cause him to lose his disguise.

For each building the Spy player places a Sapper upon, a small window in their HUD appears showing both the remaining health of the building sapped and the health of the Sapper on that building.

Once the building is being sapped, the Engineer owner is alerted to it in his HUD, and automatically plays a voice clip alerting nearby players of the building's predicament. Engineers can remove a Sapper with two hits from their melee weapon (three with the Jag). When a Sapper is attacked, the Spy player is notified by a similar alert in their HUD. If an Engineer removes a Sapper from a Teleporter, the Sapper at the other end is also removed. If a Medic is healing the Engineer, he can get an assist for the Sapper kill. Pyros equipped with the Homewrecker or the Maul can destroy Sappers in one hit (two with the Neon Annihilator). Enemies focused on removing Sappers may leave themselves open to a backstab or headshot, allowing the Spy or a teammate to distract and dispose of enemies in addition to the building in question.

The Sapper has infinite ammunition and no discernible "cooldown" time; Sappers can be placed on a building faster than an Engineer can repair the damage each one causes, which guarantees the building's destruction if the Spy is not dealt with.

Sapped Sentry Guns take 33% less damage from the Spy who applied the Sapper, such as when shooting them with a Revolver. Dispensers and Teleporters take normal damage.

Demonstration

In Mann vs. Machine

In Mann vs. Machine, Sappers can be attached to robots, stunning them (and, if upgraded, any other robots nearby). Robots stunned this way can be backstabbed from any angle. Sappers do not damage robots - they only disable them for 4-7 seconds depending on how many Robot Sapper Power upgrades have been purchased. Giants, being immune to stun, are only slowed down and can still attack players. Sapping an Engineer Robot's buildings works as usual, however only one building can be sapped at a time.

Unlike regular multiplayer, sapping either a robot or a building requires the Sapper to recharge for 15 seconds before another one can be deployed.

The Sapper can be instantly recharged with a Ammo and Clip Refill canteen; however, if the Spy has placed a Sapper on a robot or building, he is unable to deploy it until the previous Sapper is no longer active (either all the objects it was applied to are destroyed or the effect time expires).

Unused content

  • The game files have referenced a taunt for the Sapper since the game's launch; however, the animation is not present in the Spy's animation set.
  • Prior to the March 12, 2013 Patch, the Sapper would drop gibs when destroyed; however, this feature was removed, leaving the gib models unused.

Bugs

  • If the Sapper is placed on a building as it upgrades to the next level, an additional Sapper can be placed on the building for a brief period of time. Doing so causes the second Sapper to disappear, and renders the first Sapper indestructible by melee attacks from both Engineers and Pyros equipped with the Homewrecker, Maul, or Neon Annihilator. Additionally, the sapped building functions as normal, albeit with draining health. Hauling the affected building corrects the problem.
  • The idle animation does not play during a replay, causing the needle to remain still.
  • Occasionally, if a Spy saps repeatedly one end of a Teleporter while an Engineer attempts to destroys the Sappers on the other end, the Sapper is removed from the Engineer's end and not from the Spy's end.
  • The Sappers and Sapper placement outlines on robots currently do not render, though the bomb carrier's objective border still draws around the invisible model.
  • No matter how many buildings the player has sapped, the HUD only shows one sapped building notification at a time.

Trivia

  • Sappers are considered by the game to be buildings with 100 health. As such, they are immune to Critical hits (they are not destroyed in one hit by a single critical Wrench swing) and can be created with the build console command.
  • The Festive variant has a note on the right side in French roughly translating to "Merry Smissmas, my friend!".
